Robert Pattinson attended the LACMA Art + Gala at LACMA in Los Angeles on Oct. 27, 2012. A spy tells us that despite his recent romance troubles, the "Twilight" star "appeared to be in great spirits." The actor sipped a glass of champagne while mingling with the likes of Cameron Diaz and Florence Welch of Florence + the Machine. "They were laughing and seemed to be having a good time," the spy tells us of the Brits. "Overall, Rob seemed to be in a very happy mood."
